Prostitution though illegal in Korea is a 20 Billion US Dollar industry. Foreign women from Southeast Asia and Russia are trafficked into Korea to serve primarily the US Servicemen at the Bases there. These local Korean women however service Korean men. The most notorious of all hooker districts is in Itaewon on Hooker Hill.

In a survey by Men's Health Magazine, Korean men claim to have more sex than any other nationality (over 30 countries were included in the survey) at almost 5 times a week, incidentally on the same survey, Korean women are the most sexually dissatisfied.
